Check the ATF level and check the ATF cooler lines for
leakage and loose connections. If necessary, clean the ATF
cooler lines.
Check for a loose shift cable at the shift lever and the
transmission control lever.
Improper alignment of ATF p u m p and torque converter
housing may cause ATF p u m p seizure. The s y m p t o m s are
mostly an rpm-related ticking noise or a high pitched
squeak.
Check the line pressure.
Check the ATF strainer for debris. If the strainer is c l o g g e d ,
f i n d the damaged c o m p o n e n t s that caused the debris.
Inspect the differential pinion gears for wear. If the
differential pinion gears are w o r n , replace the differential
assembly, replace the ATF strainer, t h o r o u g h l y clean the
transmission, and clean the cooler and lines. Replace the
torque converter.
Be careful not to damage the torque converter housing
w h e n replacing the main ball bearing. You may also
damage the ATF p u m p w h e n you torque d o w n the m a i n
valve body. This will result in ATF p u m p seizure if not
detected. Use the proper tools.
Install the main seal flush w i t h the torque converter housing.
If y o u push it into the torque converter housing until it
bottoms out, it w i l l block the fluid return passage and result
in damage.

Inspect the clutch end-plate-to-top-disc clearance. If the
clearance is out of tolerance, inspect the clutch discs and
plates for wear and damage, and inspect the clutch w a v e d -
plate height. If the discs and flat-plates are w o r n or
d a m a g e d , replace the discs and flat-plates as a set. If the
waved-plate height is out of tolerance, replace the w a v e d -
plate. If the discs and plates are OK, adjust the clearance
w i t h the clutch end plate.

rings. Check the spring retainer for wear and damage.
Inspect the clutch end-plate-to-top-disc clearance. If the
clearance is out of tolerance, inspect the clutch discs and
plates for wear and damage, and inspect the clutch w a v e d -
plate height. If the discs and flat-plates are w o r n or
d a m a g e d , replace the discs and flat-plates as a set. If the
waved-plate height is out of tolerance, replace the w a v e d -
plate. If the discs and plates are OK, adjust the clearance
w i t h the clutch end plate.
